attempted sp4 install on sbs2000

Archived from groups: microsoft.public.win2000.setup (More info?)

Hi
I have attempted to upgrade an sbs2000 server from sp3 to
sp4 and it fails to complete the upgrade
the message was

Message displayed to the user: An error in updating your
system has occurred.

Select 'OK' to undo the changes that have been made, or
select 'Cancel' to quit. If you select 'Cancel', your
system will be left in a partially updated state and may
not work correctly

I looked in the svcpack.log file and found these entries
